The Hopo Treff dates are in the public events calendar. The next date is 09.12.2020, on Zoom (link is in the agenda). The agenda is here. (login with firstname.lastname@example.org)
The Hopo-Treff is a meeting of VIS students where Hopo topics are discussed. The topics are mainly from the internal Hopo and less from the external Hopo. Representatives from the UK and DK sit at this session and can forward what has been discussed to the departement. Examples of topics can be found here: https://vis.ethz.ch/en/politics/current-topics/.
Everyone is allowed to come to the Hopo-Treff, everyone is free to express their opinion and everyone is allowed to add topics. If you have a topic for discussion, write an email to hopo(at)vis.ethz.ch or to any memeber of Hopo. The committee president organizes and structures the Hopo-Treff and decides when which topic will be discussed. For the past few years we held those meetings in German, because everyone there could better speak German. However, the meetings are primarly in English and only in German, if all atendees agree on that.
